This prospective, randomized, triple-blinded controlled trial compared erector spinae plane blocks (ESPB) with ropivacaine alone or with dexamethasone or dexmedetomidine in adults undergoing posterior lumbar decompression with instrumented fusion. Both adjuvants delayed rescue opioid use versus control: mean time to first opioid was 6.2 ± 0.8 hours with ropivacaine alone, 12.7 ± 2.7 hours with dexamethasone, and 15.5 ± 2.0 hours with dexmedetomidine. Pain scores were lower with either adjuvant; dexamethasone was associated with lower systemic inflammatory indices.
Key findings
- Mean time to first opioid was 6.2 ± 0.8 hours with ropivacaine alone versus 12.7 ± 2.7 hours with dexamethasone and 15.5 ± 2.0 hours with dexmedetomidine.
- Both adjuvant groups had reduced postoperative pain scores at all assessed time points.
- Dexamethasone was associated with lower postoperative systemic inflammatory indices than dexmedetomidine or ropivacaine alone.
Why it matters
The trial suggests that adding either adjuvant to ESPB can extend the interval before rescue opioid use and improve postoperative pain after lumbar fusion. The differing reported effects—longer time to first opioid with dexmedetomidine and lower inflammatory indices with dexamethasone—may help frame further evaluation of adjuvant selection, while the abstract does not provide comparative results for every opioid-consumption outcome.
What to keep in mind
Follow-up was limited to 48 hours, and the study was conducted at a single tertiary academic referral center.
